TOOL FOR HANDLING SN'IALL METALLIC ARTICLES.

SPECIFICATION forming part of Letters Patent No. 512,381, dated January 9, 18914.

I Application led April 12,1893. Serial No. 470,088. (No model.)

To all whom it may eor'wern:4

Be itknown that I, JAMES T. KEY-ES, a citif New York, have invented new and useful Improvements in Tools for Handling Small Steel and Iron Articles, of which the following is a specification.y

The object of my invention is more particularly to provide a tool for picking up and handling small spherical objects as the steel balls of bicycle wheel ball bearings which are very difficult to handle by the fingers, but which tool will also be very useful for handling various other small objects of steel and iron, and it consists essentially of a magnetized bar or core adapted for picking up and holdin-g said articles by attraction, and a nonmaguetic discharger for detaching the articles when they are to be released, all as hereinafter fully described reference being made to the accompanying drawings in which- Figures l and 2, are sectional elevations of one form of my improved tool, Fig. l shewing the conditions for picking up and holding the bail, and Fig. showing the position' for releasing the ball. Figs. 3 and l, are sectional elevations of another form'of the said tool, Fig, 3, showing the conditions for holding the ball, and Fig. l showing the conditions for releasing it. Figs. 5 and 6 are like views of an-other form of. the tool and showing the different positions. Fig. 7, is a side elevation of the form of the tool represented in Figs. 5 and G, and Figs. S and 0, are sectional elevations of another form, Fig. S showing the conditions for holding the ball, and Fig. 9 the conditions for releasing it.

However the tool is constructed the essential features of it are a magnetic bar or core for lifting the objects by attraction, and a non-magnetic discharger for detaching them which are readily movable relatively to each other to permit the magnet to be presented in suitable proximity to the articles for taking them up by attraction, and for removing the articles out of the field of magnetic attraction for releasing them. In Figs. 1 and 2,(trepresents a magnetized 5o core of the tool having a central longitudinal bore I), and vbeing inclosed in a tubular stock or handle c, of non-magnetic substance having a head d, at one end znd being closed with a non-magnetic plug e, at the other end to secure the core; f, is a piece of soft iron tted to slide in and out of a socket g, in the plugged end of the stock; h, is a rod extending up through the core a, and the head of the stock and havinga head i, above by which to pull the piece of soft iron inward of the socket, andy' is a coiled spring applied to the rod h, between the shoulder k thereof, and a shoulder Z, of the head of the stock suitable for projecting the soft iron piece f, outward of the socket. of the tool the soft iron piece is drawn upward into the socket as in Fig. l through lift- In the operation of this form ing it by the head ot' rod 7L, in which position it is temporarily magnetized by the magnetic core a, and will pick up small steel or iron objects as balls m, and hold them fornse, and when the head t', is released and the rod let go the soft iron piece f, being projected by the spring outward from the socket g beyond the magnetic inlluence of .the core @,Will release and eiiect the discharge of the objects holding it.

ln Figs. and the magnetic core Ct is an ranged to slide in the stock c so that the end- I oruse in picking up the objects maybelush with the end of the stock for taking eiect, as in Fig. 3, and may be withdrawn .a suitable distance within the end ot' the stock as in Fig. 4 for releasing the balls. rlhe lifting head 't' and the spring j are in this case applied to the magnetic core, said core having the shoulders 7c for the spring, the other shoulder for said spring being on the head d of the stock same as in Figs. l and 2. The other end of the stock and the corresponding end of the core are tapered a little to limit the outward thrust ofthe core by the spring,but any other approved means of effecting such limitation may be employed. In this form of the tool the core is pressed downward bythe spring to the position for effective use as in Fig. 3, and it is lifted up by the head as in Fig. 4, for the release of -thepobjects being handled, by withdrawal of the end so far within the case that the objects, prevented from following it by the end of the stock, will be relieved of the magnetic influence.

made fast to the stock c, by the studs n, with an intermediate sliding tube o, having slots p, for the studs and containing aspringj' above theA upper end of the core 'tending to shift it upward, also having the upper end q extending above the stock a suitable distance to serve for pressing the tube downward by the finger, and also having the lower end in snitable rela'tion to the operative end of the mag-l v net for allowing it to take effect when raised by the spring on the objects to* be handled, and for discharging them when pressed down.

In Figs. 8 and 9, the stock c', core a and sprin g j, are substantially the same as in Figs. 3 and 4, with a stud s, projecting through a slot t, in the side of the stock for raising the magnet for discharging the objects held by it.

It is manifest that besides these various forms of the tool other equivalent forms may be made.

I claim- 1. The combination of the magneticbar or core and the non-magnetic discharger movable relatively to each other for permitting the core to be presented to the objects to be vmanned, ne for demhingsaid objects by the dscharger snbstantiallyas described.

' 2. The combination of the magnetic bar or core, the non-magnetic dscharger and a stock 3o or handle, said core and discharger movable relatively to each other for presenting the core to the objects to be handled,y and for detaching said objects by the discbarger substantially as described.

3'. The combination of the magnetic bar or core, the nommagnetic discharger movable relativelyv to 'each other for presenting the core to the objects to be handled, and-for detaching the said objects by the discharger, a spring for effecting the movement in one direction and a push-piece for ee'cting reverse movement substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 8th day of April,
